Description

The utility model relates to attractions simulating an artificial sea wave.

There is a known attraction according to RF 186805 U1, in which there are support walls, an elastic working surface with reinforcing pipes stretched between the walls, and the elastic working surface is made in the form of a canvas, and on the longitudinal walls there are brackets for the transverse tension of the canvas with a carriage that can be moved by means of transmission screw nut. This attraction has the following disadvantages: there are no means for longitudinal tension of the canvas, and if the canvas is not stretched in the longitudinal direction to the required value, then the tension in the transverse direction may not give the necessary results, the canvas itself is not durable, and the design of the bracket for lateral tension of the canvas in parts the screw-nut mechanism is not reliable to hold the required blade tension.

The technical result consists in increasing the reliability and durability of the water attraction simulating an artificial wave due to the use of means of longitudinal tension of the web, changes in the design of the web itself and a new design of brackets for lateral tension. Together, this ensures the achievement of the specified technical result.

The technical result is achieved by the fact that the device for tensioning the web in a water attraction having support walls, an elastic working surface in the form of a web with reinforcing pipes, stretched between the walls, contains on the longitudinal walls brackets for the transverse tension of the web with a carriage that can be moved by means of transferring a screw nut, on the transverse walls there are brackets for longitudinal tension of the web, which are made in the form of U-shaped clamps covering the reinforcing pipe, with a counterplate in which a threaded rod is located, the other end of which is fixed with a lock nut in the bracket for longitudinal tension of the web, while the running the screw of the screw-nut transmission is located without the possibility of longitudinal movement in the bracket, and the carriage nut is made of bronze. All elements of the brackets, except for the bronze nut, are made of stainless steel.

The utility model is illustrated by drawings, which are shown in:

fig. 1 - lateral tension bracket;

fig. 2 - longitudinal tension bracket;

fig. 3 - bracket with nylon strips.

The water attraction "Artificial Wave for Surfing" is a reinforced concrete structure with equipment installed in it to create a stream distributed over the working surface for riding.

In the front and rear of the attraction there are composite drain grates, protected by a deck that prevents damage from falling skaters.

The attraction consists of 2 platforms, upper and lower, between which there is a 2-layer working canvas made of reinforced PVC. The platforms are made of stainless steel, rigidly fixed in a reinforced concrete structure. In the front and rear parts of the attraction along the longitudinal axis there are support beams for the working bed, rigidly connected to the frame and additional spacers fixed to the reinforced concrete structure. To evenly distribute the load when stretching the canvas, a pocket is provided in its structure along the entire perimeter, into which a reinforcing pipe ∅ 60 × 3mm is installed.

On the side longitudinal walls of the reinforced concrete structure, the brackets for the transverse tension of the canvas are installed. They are made of stainless steel and carry a carriage 1 with a cracker for fastening the nylon belts according to Fig. 3, and in the center of the cracker there is a through hole, which is necessary for fixing the belt, which makes it possible to exclude belt slippage when the web is tensioned. The carriage has the ability to move by means of a screw-nut transfer, the screw 2 moves the carriage 1 by means of a nut 3 made of bronze. Bronze is necessary for the carriage 1 to move easily over the screw 2 and to prevent such an effect as "biting". Unlike the prototype, the screw does not have the ability to move longitudinally, but is fixed in the bracket with the ability to rotate at points 4 (head of the lead screw) and 5. Two-point fastening of the lead screw increases reliability, because severe wear of the screw mechanism is prevented by neutralizing the bending moments arising from the tension of the blade and the screw itself from breakage.

The carriage moves along the X guides, which have stiffening ribs Y, which eliminates skewing during movement.

Longitudinal tension of the web is carried out by brackets 6 made of stainless steel, consisting of U-shaped clamps 7, covering the reinforcing pipe 8, with a counter plate 9, and having a threaded rod 10. The tension is fixed by locknuts 11 as shown in FIG. 2.

FIG. 3 shows a diagram of the lateral tension of the canvas 12, made of 2-layer reinforced PVC, which also increases the durability of the attraction without tensioning operations.
